Application filed August 16, 1920. SerialNo. 403,898.

To all whom it may concern:

Be it known that I, LOUIS F. EDWARDS, a

citizen of the United States, residingv at The present invention relates to impiovements in wire stretchers, and has for an object to provide a wire stretcher that is simple in construction and economical of manufacture, at the same time being durable and cessive hnk, as indicated 1n Fig. 2.

efiective in operation.

A further object is to produce a. comparatively light wire stretcher that will enable an effective gripping of the chain usually employed in the operation of devices of this character.

lnthe accompanying drawings form ng a part of this application, and in which similar reference symbols indicate corresponding parts in the several views:

Figure 1 is a fragmentary view with parts shown in elevation of a wire stretcher constructed in accordance with the present invention.

Fig. 2 is a sectional view through the clamping device.

Fig. 3 is a fragmentary plan view of the claws; and h I Fig. 1 is a perspective view of one of such claws.

Referringinore particularly to the drawings, 1 designates mesh wire forming, for instance, a fence, and 2' designates the usual chain which is affixed to a post or other stationary object. p

In accordance with the invention a clamping device is associated with the wire 1,

and this clamping device preferably embodies a pair of elongated thin plates 3 "and 1 preferably, though not necessarily, of oak, which are clamped upon the end of the wire 1 by means of bolts 5. Straps of iron or other metal 6 and 7 are 'afiixed to the inner faces of the platestoone side the bolt holes so that these straps take up the wear andcome directly in contact with the wire.

One of the plates 4: carries an eye-bolt 8 to which to connect the hook 9 of the. lever or handle 10. A link 11 engages perforations in the link and handle as shown in position.

DH? a loose pivot point;

other llnks

12 and 13 are connected to eyes inthe ha'ndlelO at 7 opposite sides of the pivot point and serve to loosely connect the claw bars 1 1 andlo.

in order to give the handle or lever P T T OFFICE.

These claw bars are made preferably of metal and are twistedadjacent their outer ends, as indicated at 16' and 17 and have formed thereon the claws l8 and 19 extend ing from the twisted portions 'ofthe bars;

As shown in Fig. 4, the claws may be two in number on each bar, and may be separated by .a space 19 which issubstantially of the width of the Hat side of one" of the links of the chain 2, so that the clawmay engage the adjacent edge of the next suc- In use the plates and 4 are clamped about the end of they meshwire 1 inthe manner indicated in Figs. 2 and 3, and the lever or handle 10 is connected to the clamp by means of the eye 8 and hook 9. The claws are then placed in operative relation with the chain 2 and the handle 10 is worked back and forth so that the claws alternately engage with the chain2; the chain 2 being connected to a stationary post or the like,

will serve as a suitable abutment through The peculiar twist given to the

bars

14 and 15 unables the

claws

18 and 19 to be brought in a proper position relatively to the chain 2 plex apparatus to be used, or any great the making of th'e'saine.

The manufacture of the clawsyfrom flat bars of metal of a character that maybe i I 100 twisted, gives the opportunity to employ double claws of a width and strong character which effectually engage the chain. 2 Perforations 20 are provided in the lower end of the handle to which to attach operating cables if desired, so that the handle may;

be pulled thereby in oppositedirections. The claws are inclined so as to ride over the chain links in moving back to initial It is obvious that those skilledin the art may'vary the details of construction and arrangements of parts without departing without causing complicated structures to be required or a difficult come amount of time or skill to be employed in fore I do not wish to be limited to such fea' tures except as may be required by the claims.

I claim:

1. A wire stretcher comprising a lever, and a pair of claws loosely carried by the lever at opposite sides of its fulcrum point, said claws composed of flat bars bent at substantially right angles and provided with double and spaced teeth extending laterally therefrom, substantially as described.

2. A wire fence stretcher comprising a lever, a pair of claw bars loosely pivoted to the lever at opposite sides of" its fulcrum, said claw bars being bent through substantially right angles near their cute ends and having spaced apart'teeth extending of claws connected to said lever at opposite sides of itsfulcrum point, said claws com- ")risin each a fiat bar havin one end i a 2:

thereof bent over at substantially rightv a11- gles to the plane of the body of the bar and having bent teeth spaced apart by an intermediate slot extending downwardly from said bent portion of the bar, said claws being of difiercnt lengths to engage at successive points on a chain or the like substantially as described.
